echo "This is the final result of my first script. It worked how I thought it would, or hopefully have the resources to figure out why it didn't" >> name.out  # this will add another line of text to the name.out file.
# feel free to add up to 7 more lines to your commands file here using the cat/ls/pwd/mkdir/other commands that you know.
# beware using cd commands here as it will change your directory as if you were doing it on an interactive node and may cause you to reference files that don't exist

titleBest practice consideration for working with nano

In the next code box you see the top line is commented out but says to hit 'ctrl-o' 'ctrl-x' to write and exit nano.

Since files that you open with nano are able to be edited immediately, it is a good idea to get in the habit of only saving files when you explicitly know you meant to edit them with the ctrl-o command (control + o) and then when you hit ctrl-x (control + x) nano exits gracefully.

Conversely, if you open a file with nano with the intent of just looking at it or decide not to make any changes, or want to get rid of all your changes, you can hit ctrl-x and exit nano without saving the changes.

If you instead choose to exit nano with ctrl-x and then select 'save' you risk building a habit of always saving when you exit and thus may introduce edits to your files you didn't mean to.

titleSave the changes you made to the commands file, and submit your first job
linenumberstrue
# write and exit nano now ctrl-o ctrl-x
launcher_creator.py -n "my_first_job" -j commands -t 00:02:00 -a "UT-2015-05-18" # this will create a my_first_job.slurm file that will run for 2 minutes
sbatch my_first_job.slurm  # this will actually submit the job to the Queue Manager and if everything has gone right, it will be added to the development queue.
